Description
Technical field
The invention belongs to pesticide herbicide fields, and in particular to be a kind of with flumioxazin and diflufenican be to live
The Synergistic herbicide compositions of property ingredient and its application.
Background technology
Currently, chemical weed control is means the most cost-effective, wherein acetolactate synthestase in China's Production of Winter Wheat
(ALS) inhibitor class herbicide, acetyl-CoA carboxylase (ACCase) inhibitor class herbicide are China's wheat paddocks main two
Major class herbicide kind.But as the long-time of herbicide is largely applied, China's weeds of wheat includes amur foxtail, big fringe
Amur foxtail, Wang grass, hard grass, Descurainia sophia, shepherd's purse, clearvers, ox chickweed etc. successively produce the two major classes herbicide serious anti-
Property, this seriously constrains China's improving yield of wheat, stable yields.And screen the surrogate-data technique of other action targets and carry out mixture, become
Prevent and kill off one of the effective means of resistant weed.
Flumioxazin (Flumioxazin) belongs to cyclic imides class herbicide, is proporphyrinogen oxidase inhibitor, choosing
Selecting property contact killing type herbicide, can be not only used for soil treatment, it can also be used to cauline leaf process.It is chiefly used in preventing and kill off peanut, soybean, Cotton Fields
It is mainly used for preventing and kill off annual broadleaf weed and part grassy weed such as dayflower, Siberian cocklebur, piemarker, purslane, pivots storage, horse
Tang, Amaranthus retroflexus, eleusine indica, lamb's-quarters, pale persicaria etc. also have certain inhibiting effect to barnyard grass, green bristlegrass, wild oat etc..In English
State, the ingredient have been registered for preventing and kill off winter wheat field weeds.
Diflufenican (Diflufenican) belongs to substituted pyridinyl acyl aniline herbicide, inhibits plant carotenoids
Element synthesis, leads to Destruction of Chlorophyll and cell rupture, is used for soil treatment.It is wealthy for preventing and kill off most of grassy weed and part
Leaf weeds, including amur foxtail, annual bluegrass, lady's-grass, barnyard grass, eleusine indica, dog tail, Amaranthus retroflexus, shepherd's purse, purslane, clearvers etc., it is right
Broad leaved weed preventive effect is better than to grassy weed.
Invention content
The technical problem to be solved in the present invention is to provide one kind effectively preventing and kill off the anti-ALS or ACCase inhibitor class weeding of wheatland
The safe efficient Herbicidal combinations of agent weeds can prevent and kill off grass family and broad leaved weed simultaneously without antagonism between each ingredient.
Technical solution of the present invention is realized by following measures：

Stubble remains without after, is the ideal scheme for solving the problems, such as wheatland resistant weed.
Specific implementation mode
Term as used in the present invention generally has those of ordinary skill in the art usual unless otherwise specified
The meaning of understanding.
With reference to specific embodiment, and with reference to the data further detailed description present invention.Following embodiment only be
It illustrates the present invention, rather than limits the scope of the invention in any way.
Embodiment
One, indoor proportioning joint toxicity measuring
For trying weeds：Amur foxtail , Wang grass, Descurainia sophia, shepherd's purse.
Experimental condition and the culture for trying material：The culture of experiment examination material, 25~35 DEG C of temperature are carried out in illumination box.It will
Quantitative amur foxtail , Wang grass, Descurainia sophia, shepherd's purse presprouting of seeds are sowed at after showing money or valuables one carries unintentionally in the plastic tub of diameter 8cm, 1~2mm of earthing,
It is put into the pallet equipped with water, allows water gradually to penetrate into, it is for use that illumination cultivation room is transferred to after waiting water to be seeped into native table.
Reagent agent：99.2% flumioxazin active compound, extra large Lier Chemical Co., Ltd provide；98% pyrrole fluorine acyl grass

It is dissolved with dimethylformamide (DMF), required concentration is diluted to 0.1% Tween-80 aqueous solution.
Instrument and equipment：ASS-4 type automatic rations spraying system (National agricultural information project Technical Research Center).
GA110 type a ten thousandth electronic balances (Germany)；ZDR2000 intelligent datas recorder (Hangzhou Ze great Instrument Ltd.)；SPX
Type Intelligent biochemistry incubator (Ningbo Jiangnan instrument plant).
Test dose designs：It is shown in Table 1.
1 reagent agent management of weeds test dose of table designs (dosage g ai/hm2)
Application method：It tests and is sowed after weed seed shows money or valuables one carries unintentionally, then rear soil even spraying processing.Weeds are uniformly put
It is placed on area 1m2Platform on, with ASS-4 type automatic rations spraying system (in National agricultural information project technical research
The heart) spraying, Teejet 9503EVS Fan spray heads, spouting liquid 450L/hm2, atomisation pressure 0.275MPa, 4 repetitions.
Weedy rices method, time：It weighs each processing weeds aerial part fresh weight within 20 days after dispenser, calculates fresh weight preventive effect.
Drug effect computational methods：Theoretical fresh weight inhibition rate (the E of each processing blend compositions is calculated with Gowing methods0=X+Y-
X*Y/100), then compared with actual measurement inhibiting rate (E), the mixed synergy type to weeds of both evaluations works as E-E0Value
It is synergistic effect more than 10%, be antagonism less than -10%, is addition between -10%~10%.
2 flumioxazin of table is mixed with diflufenican to grassy weed control effect and synergy effect
3 flumioxazin of table is mixed with diflufenican to broad leaved weed control effect and synergy effect
Composition provided by the invention has outstanding preventive effect to grass family and broad leaved weed it can be seen from upper table 2,3, and
And flumioxazin and diflufenican can be improved to the preventive effect of amur foxtail, Wang grass, Descurainia sophia, there is apparent synergy to make
With.Because two kinds of active ingredient mechanisms are different from ALS and ACCase inhibitor class herbicides, therefore, it is anti-to can be used for wheatland
The improvement of property weeds.
Two, field control effectiveness test：
Each ingredient of each composition and content according to the form below correct amount, through high speed shear, wet grinding is made after uniform filtration
Composition suspending agent 1~6, is shown in Table 4.Comparison medicament is：50% flumioxazin wettable powder, 50% diflufenican can divide
Shot agent.Soil moisture is moderate, and soil moisture content is good, and soil treatment, spouting liquid 450L/hm are immediately carried out after wheat cultivation2.40 days
Fresh weight preventive effect is investigated afterwards.
